Final answer:
The statement is false. The success of weight loss and maintenance depends on individual factors, not solely on body weight.
Step-by-step explanation:
The statement given in the question is False. It is not necessarily true that an obese person who goes on a conventional diet has a greater chance of losing weight and maintaining the weight lost than an overweight person who does the same.
Weight loss and maintenance can be influenced by various factors such as genetics, metabolism, and lifestyle choices. While conventional diets can be effective for some individuals, the success of weight loss and maintenance depends on many individual factors and cannot be generalized solely based on body weight.
It is important for individuals seeking to lose weight to consult with healthcare professionals or registered dietitians to develop an individualized approach that suits their specific needs and goals.
